I wouldn't consider an 18/2 competent.
Defo open utg for more. I open ep 4x, mp 3.5x and lp 3x. If I know the blinds won't raise with anything but the goods I'll 2.5x or even min raise from the button.
I think raising the flop is right, otherwise we're giving great odds to any draws. We're way behind when sb shoves.
Don't post results.
